Blog #293 Eyes to the Sky Times Seven

Thanks to Discover Cayuga Lake, a topnotch local nonprofit environmental educational  organization focusing on the ecology and cultural importance of Cayuga Lake and its  watershed, I had ample help this summer studying our local Osprey population.  Through Discover Cayuga Lake’s intern program, I was fortunate to work with six very  capable environmental studies students on my Osprey research and outreach work: Elsa Brenner (Boston College), Julie Garrow (Cortland State), Maggie Lachance

(Hobart and William Smith Colleges), Kaylin Lemajeur (Cornell University), Jonathan  Rhudy (University of Vermont), and visiting from Liberia, Patience Koenig (Wells  College).

Discover Cayuga Lake is using Ospreys— the perfect charismatic megafauna for the  job— as a vehicle for teaching the community the importance of protecting the lake’s  water quality. As apex predators of their aquatic ecosystems, Ospreys are vulnerable to  hazardous substances added to the waterbody where they fish. These hazards  bioaccumulate in the bird’s fat, making them vital bioindicators of the health of their environment. (This concept is explained in detail in Blog #290 Ospreys Warn Us of  Environmental Dangers.) Thus, Salt Point’s Orpheus and Ophelia, and the entire colony  nesting around Cayuga Lake, are living indicators—and an important warning system— of our lake’s good water quality and healthy ecosystem.

Interns Elsa, Julie, Maggie, and Jonathan collected data for a study on the little known  post-fledgling period of the Osprey, which encompasses two weeks before their first  flight plus the following month or until the birds learn to fish proficiently. The behavior  and energetics of fledglings Hope and Lucky will be quantified and evaluated using field  observations taken at Salt Point combined with their activities in the nest as recorded by  the Salt Point Osprey Nest Cam. Hundreds of hours of video footage will be analyzed to  develop a picture of this post-fledgling period. The interns eagerly worked successfully  as a team to develop ideas to improve our record keeping and methodology. An article  on this study will be forthcoming.

Discover Cayuga Lake fosters appreciation of Cayuga Lake to promote its stewardship.  To further this, interns Patience and Kaylin converted sections of the Cayuga Lake  Osprey Trail into a guided lake tour using the PocketSights app. This upcoming PocketSights cell phone-based guided tour includes a selection of easily viewed Osprey  nests around the lake along with nearby wineries, restaurants, ice cream stands, and  venues of cultural, historic, and natural interests to encourage birders and other visitors  to explore the area and indulge in its many delicacies.  

In addition to its regular eco-cruises, specialty sunset ventures, and community seminar  cruises aboard the M/V Teal, Discover Cayuga Lake also offered popular Osprey eco cruises 2–3 times a week this summer, focusing on sightings of the Ospreys nesting in  the southern end of Cayuga in Stewart Park, the Inlet, and Treman Marina Park.

To enhance their intern experiences, Elsa, Maggie, Kaylin, and Patience all served as  intern tour guides on the Teal’s Osprey cruises offering their insights gleaned this  summer.

It was a sincere pleasure working with these bright and promising young people, and I  look forward to seeing what our data reveals. I wish them all the best as they resume  their studies and in their future careers working for environment.  

Pardon for the lateness of this post—I was in the Adirondacks studying Ospreys. 

Eyes to the sky!

Blog #461 Sneak Peek at Osprey Season 2024

Image

Our northeastern Ospreys return to their breeding habitats just after the early spring thaw. This year’s first Osprey was seen in Cayuga Lake Basin on March 15, an early date many attribute to  the mild winter. Most nest occupants will have returned to their nests and reunited with their mates by this weekend. These returning Ospreys have just completed their 2,000–4,000-mile migrations from their wintering areas along the coasts of South America and in the wild Amazonian tropics. The range of landscapes that a cosmopolitan Osprey can experience in its lifetime is staggering. In general, the older breeding males arrive on their nests followed by their mates in a few days. After that first wave of older Ospreys arrive, unmated adults and second-year birds migrating north for the first time after spending two years in the S...

Blog #397 Halfway Mark: Three Weeks

Image
  On Osprey Time On Osprey Time just moved to blogger.com. Pardon the delay in posting.  Please bookmark! A mother feeding her 3.5-week-old offspring, courtesy of Cynthia Sedlacek.   Three and a half weeks into the nestling period, the three chicks have grown halfway to their adult size with Moana, the eldest, weighing just shy of a pound. Full-grown adult males usually weigh 2 pounds and females can be up to 4.4 pounds. Sleeping through most of the day and all night, the pile of offspring springs to life whenever their father, Orpheus, brings a fish to the nest. When awake, the nestlings waddle around the nest with their enormous feet, defecating over the nest edge, and peering over the rim at the people below. They are starting to use their wings for balance and rock forward on them to get a good stretch. When it’s mealtime, the eager chicks make their way across the nest to get fed by their mother Ursula.   Once their crops (storage organs; see second photo below...

Blog # 474 Not an Empty Nest

Image
  Ursula and two of her offspring waiting for Orpheus to arrive with food, courtesy of Cindy Sedlacek. With the fledglings flying about, the nest looks empty, and it is most of the day. However, the nest is still a noisy family meeting place for meals and a refuge for sleeping fledglings. The siblings’ days are spent practicing important survival and life skills derived from combinations of instinctive (nature) and learned (nurture) behaviors. Ursula takes it easy in the shade of the cottonwoods as she is no longer needed by her family. She’s begun feeding herself to make up for the weight she lost over the breeding season and visits the nest at mealtime happy to nibble at a fish. After she has regained her strength, she will migrate to her wintering spot somewhere in South America, dodging hurricanes along the way. At noon today, Ursula went to the nest calling for food. She was joined by fledglings O’Connor, O’Leary and O’Shea in an ear-piercing chorus of begging that probably tr...
